[mythtv] Frontend dying on aspect ratio change
lists at wildgooses.com

The following snippet from one of my recordings *usually* kills the
frontend at the point the aspect ratio changes from 16:9 to 4:3 (just as
http://www.wildgooses.com/downloads/duff.nuv (around 7Mb and FWIW: it
came from a dvb-t device)
I'm having difficulty debugging it though. It doesn't *always* die for
starters (but > 50% of the time it does). Also, gdb is acting rather
wierd for me, "thread apply all bt full" is just doing nothing (although
"bt full" still seems to do something) - I have tried updating to gdb 6
and a newer 2.6.5 kernel, but no change..? I also can't see how to get
gdb to stop just before the app dies, and so I can't see how to find out
which line it is actually excuting on? (It's not dying like a segfault
would) Finally, whats with all the Sig32 signals in the most recent cvs
version? Is "handle SIG32 nostop" the way everyone else supresses them?
As near as I can tell though, it's probably related to the "unknown
conversion" error messages coming back (which seem to be in the OSD
code), and the "GetNextFreeFrame() served a busy frame" messages.
However, these don't reliably turn up every time. Could it in fact be a
chunk of code which isn't handling SIG32 signals though (hence the
reason it doesn't happen everytime, bit of a race condition)?
Any help appreciated
